Vedclass · Answer

(A) The reaction $R-CONH_2 \xrightarrow{NaOBr} R-NH_2$ is the Hofmann bromamide degradation reaction. In this reaction,the alkyl or aryl group $R$ migrates from the carbonyl carbon to the nitrogen atom. This migration occurs with complete retention of configuration at the chiral center of the $R$ group. Since the starting material has the $Ph$ group at the top,$CH_3$ on the left,$H$ at the bottom,and the $CONH_2$ group on the right,the resulting amine $R-NH_2$ will have the $NH_2$ group in the same position as the original $CONH_2$ group,with all other groups $(Ph, CH_3, H)$ remaining in their respective positions. Comparing this with the given options,the structure in image $817-$a132 represents the correct product with retained configuration.

The major product of the reaction is:
$R-CONH_2 \xrightarrow{NaOBr} (A)$
(where $R$ is the chiral group shown in the image)
